The invention relates to improvements in muiilers for deadening the noise and checkin'g the pressure incident to the blowing oil of boilers, and while the presentdisclosure is directed to a locomotive blow-off muilier, it will be understood that the invention is applicable also for use in connection with stationary boilers.

It is one object of thein'vention to provide a` device of the class Idescribed which embodies a new and improved muiiling means Aformed by a multiplicity of apertured sheets (preferably woven wire) disposed'side to side in compact relation.

The muiiling massformed by the apertured sheets, is disposed within a casing, which casing is provided with an inlet for the water, sediment and the like from the boiler, and is 'apertured for the discharge of the water and any materials carried in `suspension thereby. It is a 'further object oi the invention to provide the inlet in the form of` a 'pipe and `to extend itinto the muiiiing mass so that the fluid discharged from 'said pipe may spread-in numerous directions in the mass-before reaching the atmosphere.

A still further aim is to so construct the casing .as to permit easy insertion or removal of the apertured muilling sheets.

Yet another aim is to' provide a lmutller whose casing is so constructed that forcible downward discharge cannot Vtake place when the boiler is beine` blown oit, so that'there is no-danger of lowing 'any of the' truck ballast'out of position.

With the foregoing in view, the invention residesin the novel subject matter herein'- afterV described and claimed, the description. being' supplemented by the accompanying drawing.

Fig. 1 is a side elevation showing the invention applied to a locomotive.

V2 iis whoriz'tal. sectional. view on line 2-2 of Fig. 1.

Fics-3 and 4 are vertical sectional"views gn the correspondingly numbered lines of ig.2.1l Fig. 5 is a view similar to Fig.- 3 but ilF lustrating the manner in 'which the muler sheets may be readil inserted or removed.

In the drawing 'a ove briefly described,

the numeral 6 designates a rectangular casing whose bottom 7 and-two of its vertical sides 8 may well beformed from a single metal plate, as shown in Figs. 3 and 5, its

other verticalfside 9 being then formed from 4separate plates welded to the sides 8 and the bottomv7. In the present showing, the bot- -tom 7 and one of the sides 9, are providedvk with a multiplicity'of perfor-ations" 10 for the discharge of the dirty Water blown oi from the boiler.

' I have` shown outstanding flanges 11 on the upperends of all ofthe sides 8 and 9, a'nd a top"1. 2 is removably secured by bolts 13 to these flanges. A.. hanger '14 for the entire device, may well be secured to this top by bolts 15.

r 16 denotes amultiplicity' of flat, apertured sheets preferably formed of Woven Wire, said sheets being disposed side to-side in contact with each other and forming a inuilling mass which entirely fills the casing 6. These sheets are disposed inplanes ,at right angles to -the removable top 12 and about half ot them are formed with registering openings 17 which register also with an opening 18' in oneof the sides 8. A blow-oif pipe 19, sultablyconnected with the boiler 20` and provided with one or more appropriate charge through'the'perforations 10.A When traveling in this manner, the force of the water is cheeked and the noisel which would otherwise occur, is eectively deadened.

When inserting the sheets 16 into the casing 6,.thos`e having theppenings 17 are tirati-passed into the easing, the top 12 being then of course. detached. These sheets are' moved 'into'the portionv of the casing' t van.. sheets are 17. then receive the pipe. .When these sheets mhepipenndsad. then slidl intov the pipe-containing" portionI of the casing, so that their openings' have been inserted, the remaining sheets may be readily placed in position and the cover. plate 12 then secured in pace.

Downwardly spaced, om the -I have shown' an imperforate plate 2 2 which is provided with '-anges'23. of im rforate nature. There are three of these' anges in the present disclosure and they are welded or otherwise secured to the casing sides 8 and 4bottom 7,

one of the sides 9, there being no flan e however at the-side 9 which is perforated. This side of the device, when the latter is used upon a locomotive, is preferably dispos/ed toward the rear of the latter but this is not absolutely essential. However, it will be seen that the plate 22 prevents the water discharged through the perforated bottom, from forcibly striking the track ballast and Washing any thereof out of place. Then too, by having perforated plate 9 disposed toward thel rear or even toward the front of the locomotive tlere is no danger of the scalding water discharging laterally and causing injury to any nearby person.

casing, .and a water blow-ofi'v pipe enteringy -the casing, passlng through .a' plurality of the sheets ofvsaid series and terminatingbetween the ends of 4said series.

2. A boiler blow-'olf muler comprising a rectangular casing apertured for the discharge of water and having a removable side, a water inlet pipe projecting inwardly from a side of said' casing at right angles to said removable side, .said water inlet pipe extendinginto said casing .to substantially a central point, a. multiplicity' of apertured rectangular -sheets 'disposed side-to-side in and `an inlet;- an i'mperforate plate spaced planes at right angles lto said-removable side of said casing, substantially half of said sheets Abeing formed with registering openings receiving said inwardly projecting pipe, while the-remainder of said sheets are free from such openings, the sheets having said openings being shiftable from said pipe into an opposed portionof the casing, after remo'val of said remainder of said sheets from saidcasing portion.

3. A 'boiler blow-0E mulller comprising a 45a rectangular casing apertured for the discharge of Water and having a removable side, a multiplicity of' apertured sheets". disposed side to side in planes at right angles'v to said removable side and forming a muing mass which fills, the casing, a 'side of the casing at right angles to said removable side being formed with an opening, a plurality of said sheets being also formed with openings which register-with each other and with o. 4

the first named opening, and a' blowlof pipe passing into the casing andfthe aforesaid muliing mass through said registering openings, said sheets being removable from the casing after removal of said removable casing side. l I

4. A boiler. blow-olf mulller comprising a casing, mulig means completely filling said casing, said casin 4having Va vertical side provided substantially `throughout its area with al multiplicity of '.perforations, a bottom also provided substantially throughout4 its area with `amu1tiplicity ofperforations,

below said bottom, and mperforate flanges rising from said plate to all vertical sides of the casing'except said perforated side, the space between the lower lend of said per' forated side andsaid bottom entirely 85 open. l
